To all whom z'tmay concern:

Be it known that l, Hans M. HANSEN, a citizen of the United States, and resident of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Treads, of which the following is a specification.

This invention relates to outer soles of boots and shoes, and particularly to such outer soles as are made of elastic material usually called rubber, the sole being stitched to the bottom of the shoe.

My invention has for its object to enable an outer sole provided with a heel formed integral therewith to be secured to the shoe bottom entirely by stitches. v

The invention consists in the improvements which I will now proceed to describe and claim- Of the accompanying drawings forming a part of this specification: Figure 1 represents an edge view of an outer sole embodying my invention; Fig. 2 represents a section on line 2-2 of Fig. 1; Fig.3 represents a section on line 33 of Fig. 1; Figs. 4 and 5 represent respectively a bottom and a side view, showing the sole represented by Fig. 1 stitched to the bottomot a shoe; Fig. (3 represents a view similar to'a portion of Fig. 5, showing a portion of the margin of the sole reduced or trimmed.

The same reference characters indicate the same or similar parts in all the views.

The sole embodying my invention shown by the drawings includes a fore portion 12, a shank portion 13, and aheel portion 14, these portions being formed in a single piece of elastic material such as is commonly used for so-called rubber heels and soles. The margins of said portions are continuous with each other and form a rela tively thin continuous marginal attaching portion 15. The thickness of the marginal portion15 is suchtha't it is adapted to be secured to the bottom of a shoe by stitches 16 formed by a stitching machine, the stitches connecting the sole with. the welt 17 of a welted shoe, as shown by Fig. 5, or with any other suitable part or parts,

such as the inwardly turned edge of the u per and the inner sole in a McKay sewed s 0e. The stitch-receiving portion .15 extends entirel around the sole, so that the entire sole, including the heel portion, is stitched to the shoe.

19 represents a heel-shaped tread formed on the heel portionlt and of smaller area than the latter, the'curved edge of the tread 19 being parallel with the edge of the heel portion and offset inwardly therefrom, so that the under face of the marginal portion and the edge of the tread 19 form a recess 21 in the angle ot which the stitches 16 are formed. Said recess therefore enables the operator to locate the stitches in a line parallel with the edge of the heel portion and close to the edge of the tread 19. The exposed portions of the stitches are protected by the sides of said recess so that they cannot come in contact with the ground until the tread is worn away. Y

The heel portion 14 may be trimmed nearly locate its final edge relatively close to the edge of the tread 19, thus: reducing the depth of the groove 21, as shown by Fig. 6, the extent to which the edge of the heel portion may be cut away being indicated by the dotted line :1: (Figs. 3 and 5). The trimmed edge and the edge of the tread 19 collectively form a stepped heel edge which does not difl'er'materially in a pearance from an ordinary rubber heel. he margin of the heel portion is thickened as shown by Figs. 1 and 4 and constitutes the upper stepof lit ,to the stitches 16 to reduce its area and the heel, the lower step being formed by the tread 19. The tore portion 12 is preferably provided with a tap-shaped tread portion 23, the edge of which is offset from the edge of the fore ortion to form a stitch-locating and protectlng recess 2L This tread portion may however be omitted it desired.

Having described my invention, I claim:

An outer sole and heel composed of elastic material and having a fore portion, a shank portion, a heel'portion, the margins of said portions being continuous with each other and adapted to be stitched to a shoe bottom,

'step of which is formed by the ofl'set tread on the heel portion.

- In testimony whereof I have afiixed my signature, in presence of two witnesses.

- HANS M. HANSEN.
